This 8 x 10 camera is more of a civil engineering project than camera building.  The main frame is built from  2" x 1" pine whilst the front and rear panels are 10 mm ply.  In this version , designed for some experimental work with paper negatives, the "optics" are fitted in a rotating turret with    f 256 and f 96 pinholes and an f 64 lens. A removable focussing scren fits in where the DDS is shown. The focus range is infinity to  2 mtrs, although this is only relevant with the f 64 lens . This is the largest diy camera that I have built, no plans exist fro anything larger
